Almost 40% of AZ coal generation retiring at the end of this year. Combine this with recent closure of units of San Juan (NM) coal plant Dec 2017 and the remaining San Juan units in 2022. Great news for cleaner electricity in the SouthWest.
This coal is being replaced with renewables and storage. One example is the recent APS announcement.
Arizona’s largest utility wants to support its renewable power portfolio by adding as much as 850 MW of battery storage capacity to its solar power plants by 2025.
Arizona Public Service Co. (APS) made the announcement February 21. Don Brandt, the utility’s chairman and CEO, in a statement said, “Arizona is already a national leader in solar energy. The challenge is, no one has figured out how to stop the sun from setting at night. As storage technology improves and declines in cost, we will increasingly be able to store the power of the sun cost-effectively to deliver when our customers need it.”
